Model 5802i can operate with external sensors to maintain better than  ±1 V balance by altering ion output and adapting to environment changes. With the optional sensor and collimator, it delivers precisely balanced and directed ionized air to the target without taking up valuable room in environment. A greater concentration of emitter points and internal circuitry suited for high humidity applications makes the Model 5802i the standard choice for environments that need quality ESD protection with solid design.
